CAR-DOOR LOCK.
j Application ined may 27, 1921. serial No. 472,999.
To all whom t may concern;
, Be it known that T, ROY MURRAY, a citizen of the United States, residing at Jensen, in the county of Uinta, State otUtah, .have
invented certain new and useful Improvements in Car-Door Locks; and I do hereby declare the ollowingtojbe a full, clear, and
Y exactdescription of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.V
. This invention relates to lnew and ,useful improvements in locks and particularly to locks for freight car doors.
One object of the invention is to provide a device by means of which a car door can be locked automatically from within. and which can be readily and easily opened from without, 'by one authorized to do so.
Another object is to provide a loclr of this character which is simple in construction, formed of few parts, and which can be manufactured at a low cost.
Other objects and advantages will be apparent from thefollowing description when taken in connection with the accompanying drawing.
In the drawing:
Figure 1 is an elevation of a portion off a car Wall and door, showing the lock applied thereto and in properly engaged position.
Figure 2 is a horizontal sectional view through the wall and door, immediately above the lock, on the line 2-2 out Figure 1.
Figure 3 is an enlarged vertical sectional view through the outer portion of the lock, on the line 3--3 of Figure 1.
Figure 4 is a horizontal longitudinal central sectional view through the lock, on the line 4-4 of Figure 1.
Referring particularly to the accompanying drawing, 10 represents the wall of a car, 11 the doorway, and 12 the sliding door, in connection with which the invention is used.
Secured to one of the vertical edges of the car wall, within the car, and extending toward the doorway, is a metal casting 13, the outer end of which is formed with an upper shorter projection 14, and a lower longer projection 15. This longer projection 15 is vertically and longitudinally bifurcated to permit play therein of the triangular latch plate 16, which is pivotally connected, at its smaller end, to the outer end of the longer projection, as shown at 17. In the opposite side portions of the bifurcation are formed with outwardly bowed portions 18 to receive thereinthe coil springs 19, the lower ends of said springs being retained by the cross members 20, while the upper ends are connected with the member 16. At the inner end ofthe longer projection. 15 is formed a vertical shoulder 21, and formed in this shoulder is a vertical slot or groove 22 in which the adjacent wider end of the plate 16 is guided. The upper edge of the plate 16 has the lateral lianges 23 on which the angle plate 24 is adapted to ride,
to rock the plate 16 downwardly, against the tension of the springs 19. This plate 24 is carried by the inner face of the door 12', at the proper distance from the vertical edge to permit the said edge portion of the door to overlap the wall of the car, at the side of the doorway. The projecting portion of the plate 24 is the proper width to pass into the space between the projections 14 and 15, and has the lateral portion 24 to engagebehind the portion of the casting 13, which prevents outward swinging movement of the door, when in closed and locked position.
From the above, it will be seen that when the door is moved into closed position, the plate 24 will engage with the triangular plate 16, and depress same so that the plate will pass between lthe projections 14 and 15. The plate 16 then moves upl and snaps behind the plate 24, thus holding the door in closed position. It will be noted that the lock is mounted within the car, so that means must be provided for opening the door, or rather :for releasing the lock, from outside of the car.
Carried by the member 13 are the grooved wheels 25, and adjacent an opening 26, in the wall of the car, there is mounted a similar grooved wheel 27. Secured to the inner end of the triangular plate 16, and passing around these wheels 25 and 27, is a chain 28, the other end of which extends through the opening 26 and is provided with a ring 29 which is adapted to be grasped and pulled to swing the plate 16 downwardly out of engagement with the plate 24, thus releasing the lock, and permitting the door to be slid into open position.
Secured to the car wall, over the opening 26, is a plate 30 having an opening 31 the wall of which is outwardly beveled, and against this beveled wall is arranged to engage the ring 29. It will be noted that the chain 28 is of such length that when the tendinfr outwardly therefrom, is a staplel;I
througi which, and through the ring, is arranged to be secured the ribbon or wire of the seal 32. By this arrangement the ring cannot be moved a dista-nee sullieient' topermitthe chain to be drawn out andthe plate 16 rocked out of engagement with the platefl. Thus the lock securely main tains the door in closed position against unauthorized manipulation.
1What is claimed is:
1. A sliding door lool; comprising aV door casing carried member having an upper shorter projection anda lower longer projection, the` lower projetion being vertically andv longitudinally biturcated, the inner end ofA the longer projection. being formed, with a vertically grooved: shoulder,
means for manually swinging the triangular plantel downwardly, andl an .angle plate adapted to be mounted on a sliding door for depressing engagement ivith the triangular plate and seating within the space between the said projections, said angle plate having an offset free end arranged to engagev behind the door casing carried member to maintain the door against outward swinging movement.
2. A lock comprisingra stationary part in cluding a bifurcated member havinga long arm and a short arm, a longitudinally extending and spring pressedl member pivotallyl mounted in the long arinandengaging the short arm with its free end, and a mov; able part arranged'to enter thebifurcation andnpi'ovided withan olf-setportion for engagement with the stationary part to preventv relativeulateral movement of the parts.
In testimony whereof@ affix my signature,
vin the presence of two witnesses'.
